【问题描述】：
我的 iOS 应用程序刚刚被拒绝，因为该应用程序将数据存储在 Documents 上，因此它由 iCloud 备份，这是不允许的，因为数据是从服务器下载的。 但即使我使用 addSkipBackupAttributeToItemAtURL 它仍然显示为 iCloud 的备份。这里是我使用过的代码
NSError *error = nil;
NSData *data = [NSData dataWithContentsOfURL:url options:0 error:&error];
if(!error)
{
[self HidePreLoader];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSLog(@"_paths--->%@",paths);
NSString *path = [paths objectAtIndex:0];
NSLog(@"_path---->%@",path);
NSString *dataPath = [path stringByAppendingPathComponent:@"/MyFolder"];
NSLog(@"_dataPath---->%@",dataPath);
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
{
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error];
}
NSString *zipPath = [dataPath stringByAppendingPathComponent:downfilename];
[data writeToFile:zipPath options:0 error:&error];
if(!error)
{
[self HidePreLoader];
ZipArchive *za = [[ZipArchive alloc] init];
if ([za UnzipOpenFile: zipPath]) {
BOOL ret = [za UnzipFileTo: dataPath overWrite: YES];
if (NO == ret){} [za UnzipCloseFile];
NSLog(@"folderPath--->%@",folderPath);
//Here i have used the use code
NSURL *guidesURL = [NSURL fileURLWithPath:folderPath];
[guidesURL setResourceValue:[NSNumber numberWithBool:YES] forKey:NSURLIsExcludedFromBackupKey error:NULL];
//The following code also doesnt work
//NSURL *guidesURL = [NSURL fileURLWithPath:folderPath];
//[self addSkipBackupAttributeToItemAtURL:guidesURL];
[self HidePreLoader];
NSString *path = nil;
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
{
path = [folderPath stringByAppendingPathComponent:@"module-B1-ipadmain-swipe-tablet.html"];
}
else
{
path = [folderPath stringByAppendingPathComponent:@"module-B1-ipadmain-swipe-phone.html"];
}
NSLog(@"path--->%@",path);
dispatch_async(dispatch_get_main_queue(), ^{
appDel.currentReadingPlanWithPath = path;
appDel.moduleDownloaded = YES;
[appDel SetCurrentDownloadPath];
NSLog(@"file download success");
[progview setHidden:YES];
[progval setHidden:YES];
[self HidePreLoader];
downloadView.userInteractionEnabled=YES;
[self SetModuleDownloaded:@"true"];
[self ShowAlert:@"Download" message:@"Success"];
[self HidePreLoader];
});
[self HidePreLoader];
}
}
else
{
NSLog(@"Error saving file %@",error);
}
}
else
{
NSLog(@"Error downloading zip file: %@", error);
}
});
AddSkipBackupAttributeToItemAtURL 方法
-(BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]);
NSError *error = nil;
BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES]forKey: NSURLIsExcludedFromBackupKey error: &error];
if(!success){
NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error);
}
return success;
}
当我尝试上面的代码时，iCloud 仍然显示 iOS7 中的应用程序。请帮我解决这个问题。

我不知道，但是文档说 “通常对用户文档进行的某些操作会导致此属性重置为 false...”，所以这就是我要检查的第一件事。
